<dl compact="compact">
<dt><em>Description</em></dt>
<dd><p>This function tests for completion of all asynchronous operations.
In C/C++, a non-zero value will be returned to indicate all asynchronous
operations have completed. While Fortran will return a <code>true</code>. If
any asynchronous operation has not completed, C/C++ returns a zero and
Fortran returns a <code>false</code>.
